N591DK

This entry covers airframe N591DK, a 2001-built Cessna Citation Encore (Cessna Citation Encore (Model 560)) bearing serial number 560-0591. The aircraft is registered in the United States and is owned and operated by IRON RING AVIATION LLC, a Portland, Oregon–based corporation. The airframe’s single documented ownership by this corporate operator is the notable registry action on record. Valuation records list the aircraft at approximately $3,400,000, reflecting market positioning for a well-equipped Model 560 example of this vintage.

The cabin of N591DK is outfitted for executive transport, featuring an executive club seating arrangement typically accommodating 7–8 pax, an enclosed aft lavatory, and a refreshment center. Avionics aboard this airframe follow the common original equipment manufacturer configuration with a Honeywell Primus 1000 suite as the typical fit, supporting the aircraft’s light business jet operational profile. Typical missions for this Encore include short- to medium-range corporate transport and on-demand charter flights within the aircraft’s 1,700 nm range and cruise speed near 430 kts, with operations optimized for high-altitude cruise up to 45,000 ft. As a corporate-owned platform, maintenance and dispatch are likely centered through the owner’s established facilities in Portland, Oregon, consistent with registry information.

The Cessna Citation Encore (Model 560) occupies the light-medium business jet niche, offering improved performance over earlier Citation lines due to its PW535A powerplants and modest transcontinental capability. Competing models in the segment include other late-1990s to early-2000s light-cabin business jets that balance runway performance, operating costs, and cabin comfort. Buyer and charter demand for Model 560 airframes typically focuses on well-maintained, avionics-equipped examples; the reported value of $3,400,000 aligns with market expectations for a 2001 airframe with OEM-style Honeywell Primus 1000 avionics and executive interior features. Maintenance and resale considerations center on engine life remaining for the PW535A units, updates to avionics for regulatory or capability reasons, and the documented corporate ownership history.
